Application filed December 23, 1910. Serial No. 598,887.

To all wimm it may concern:

Be it known that I, EDWARD E. Gow, a United States, residing in the Manhattan, city, county, and York, have invented certain Improvements in Heating the following is a specifiborough of State of. New new and useful Systems, of which cation.

My invention relates to heating systems, and will be found particularly desirable for use in heating surface cars, especially trolley cars, although it is not limited to such use and may be available for other uses.

The invention consists in the proyisionof means whereby heat may be rapidly and economically generated within a heating ipe froni which it is radiated for the heatmg of the apartment in which it is situated.

My invention may well be employed in connection with the heating system d sclosed in my application for Patent Serial No. 595,119, filed December 1, 1910, although it is not necessarily limited thereto.

A desirable form in which my invention may be embodied is illustrated in the accompanying drawings, wherein,

Figure 1 illustrates a longitudinal sect-ion of a structure, as for instance a car body, having applied thereto heating pipes constructed according to my invention; F1g.2 1s a cross-section of the same; Fig. 3 is a vertical section of an extension on the said heating pipe, and of a heater pocket formed therein and the, heater within the said pocket.

In the device illustrated in my' said prior application for patent, a heating pipe is employed which is only partially filled with vaporizable liquid, and in which the balance of the pipe contains a vacuum, and the said pipe is sealed to prevent any breaking of the vacuum.

To this end my invention consists in formlng at a point in the said pipe, and preferably at the end of a vertical part thereof which constitutes the lowest point in the pipe, a double walled extension the inner wall of which is. open to-the atmosphere on its outer end and closed at its inner end a' pocket for the reception. of a forming The thickness of the sheet of liquid heater.

contained between the two walls of the pipe,"

, at the said extension is very slight and be as little as one-eighth of an inch. The inner wall of the pocket I preferably fo 'm of a thin tough metal which is a good heat conductor, and for which purpose I ave found copper to be admirable. Withi the pocket thus formed I insert a heater ilnit, and I preferablv so construct the said device as there shall be no air insulatiori between the heating element and the inner wall of the pocket; in other words, I prefer to have close contact between the said parts, and if any spaces should exist they are refs erably filled with some suitable heat co'n-i ducting substance, as sand. For he ting purposes I have found an electric'heat r to be desirable and useful, and for the pur ose of easily obtaining different degreesof eat this heater may have two or more circuits composed of wires of different heating ca pacities, one or more of which maybe n circuit at the same time, whereby varyin degrees of heat may It will beperceived that owing to the thin sheet of water and to the intimate con tact from the heater to the same, that the fluid within the pipe may quickly be vaporized and the radiation of heat from the heating pipe will begin very shortly after the eurrent is turned on the electric heater.-

, In the particular embodiment of my invention illustrated in the accompanying drawings, the heating pipe A is illustrated as having upper portions a which are situated within the space to be heated, in this instance a trolley car, and are located beneath the seat and in front of the. riser. and

This .pipe as shown downward inclinapart a? which is behind the register a has a return bend and a tion, and terminates in a conveniently located below the car floor,

Upon this lower part is formed an extension I that my invention is necessarily limited to B, which may well be slightly enlarged, and I such features, as equivalent devices may be has secured to its outer end an inner tubusubstituted and changes made therein with lar socket & which is open on its outer end i in the limits of the appended claims. and closed on its inner end. i

A heater is placed within the partial vacuum therein and having a. small heating pocket produced by the inner socket quantity of water in its lower end, the lower Z) and heats the liquid between the walls end of said pipe forming a pocket which is of the pipe. I have found that an electric surrounded by a thin annular body of the heater is well adapted to this purpose, and have illustrated such heater in the several water, and an electric heater within'said pocket making close contact with the wall figures of the drawings. The radiating pipes are made short (two in the length of a thereof so as to quickly vaporize the surrounding thin body of water, said radiattrolley car, as shown) and of such a downing pipe being so short and being inclined ward pitch that the water of condensation. at such a pitch as to return the water of cou runs quickly down to the lower end while densation to its lower end while such water it is still hotand requires only a short time is still hot and requires only a short time and a small quantity of heat to re-vaporize and asmall quantity of heat to reconvert it it, especially in the partial vacuum which 1 exists.

It will probably be found that about a pint of water will be sutlicient. This will depend upon the diameter of the heating pipe. A pipe having 1;} inches diameter throughout its radiating portion and 52 inches diameter in the extension, I have found to be a desirable size.
